The Rubber elasticity article is fairly brief and states in the lead that it is synonymous with hyperelasticity. If that is correct (anyone?), I propose merging it in here. Thoughts? Dhollm ( talk) 21:44, 23 August 2010 (UTC)
The section Hyperelastic material#Incompressible isotropic hyperelastic materials, the part "If in addition , then..." is in my opinion wrong (did some examples, can present a counterexample, but would be interested if I am mistaken), my guess is that the assumption should read or .
But before fixing the possible typo: The information in the rest of the section is rather trivial, including the following case (equibiaxial extension, ). Why not ommit both special cases? One could easily obtain these by just substituting into the general formula. Also, other special cases could be thought of, which are not mentioned here - what makes the two so important? The -dependence is perhaps somewhat important (considering the material models in widespread use, such as neo-Hookean or Yeoh), but the individual deformation modes are already treated on the pages of some of the particular hyperelastic models, e.g. Neo-Hookean solid or Mooney-Rivlin solid.
